rain, hail, and wind happen.
A tornado usually forms from a mesocyclone, which occurs in the updraft or rear portion of some thunderstorms.
Sometimes tornadoes can evade radar detection. This most often happens if the tornado is short lived, and thus is missed as the radar beam rotates, or occurs far away from the radar. Fortunately this occurs less often with strong tornadoes.
Tornadoes most often form in the rear portion of a thunderstorm, and are generally preceded by heavy rain, thunder and lightning, and occasionally large hail.
Before it reaches the ground a developing tornado is known as a funnel cloud.
you will see Cumulonimbus clouds before a tornado which are large, dark, anvil-shaped clouds.
A tornado occurs
The tornado is a twister before it hits the ground, it just spins in the sky, kind of
The weather that precedes a tornado, including heavy rain and hail generally occurs in the front part of a supercell thunderstorm, with the tornado closer to the back.
The average lead time for a tornado warning is 15 minutes. Sometimes you get more warning, sometimes less.
It varies but most often it stops raining a few minutes beforehand. A break in the clouds may be seen, a sign of a downdraft that helps the tornado form. A number of tornado survivors recall it being unusually quite just before the tornado hits.
The area in which the tornado happens can erode the area away cause the animals that lived there to have no home or die of the tornado
It is simply a tornado. Most tornadoes occur on land.
A tornado. Tornadoes usually occur on land anyway.
When a tornado touches down it means it has reached the ground and can now cause damage. It is not a tornado until this occurs,
This often occurs because a tornado is in the updraft portion or rear ha;f of a supercell thunderstorm, while most of the wind rain and hail is in the downdraft portion or front half.
The energy is stored in the air as thermal energy. A supercell thunderstorm turns that into kinetic energy in the form of rotating wind. Under the right conditions that rotation can form a tornado.
It is rather unusual for a tornado to look like spaghetti. If a tornado does take on such an appearance it most likely means the tornado is dissipating or "roping out." It is believed that this occurs when cold air chokes of the warm air that feeds the mesocyclone, the rotating updraft that drives the tornado. When this happens the tornado begins to shrink and weaken. Winds within the parent storm can somtimes cause a tornado at this stage to bend into unusual shapes.
